Lead-free soldering term?

Can anyone tell me what the definition of a "Hot Tear" is when referring to the soldering process using Lead Free Solder?

Experts Comments

A crack in the solder joint formed by the metal pulling itself apart while cooling in the joint or a short time after its removal from the heat source. The defect is called hot tear when fracture takes place around or just after solidification of the metal. It may be known as a shrinkage or contraction crack.
